CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 10/255,519 filed on Sep. 26, 2002. The disclosure of the above application is incorporated herein by reference.

FIELD OF THE INVENTION

This invention relates to a pressurized washing system. More particularly, this invention relates to a boat-mounted pressurized washing system for permanent installation and full integration into a boat or recreational vehicle for the purposes of washing the same and surrounding areas by delivering water expelled under high-pressure.

BACKGROUND OF THE INVENTION

Pressurized washing systems are relatively common. It is well known that the washing efficiency of a liquid such as water increases when delivered to the desired object to be washed under a higher pressure stream rather than at lower pressures. One common application and desired use for a pressurized-washing means is in the area of washing boats or recreational vehicles (RV's) such as motor homes and trailers, due to their tendencies of becoming frequently defiled, from salt, insects, birds and dirt from infinite sources.

It is old in the art to provide a portable means of supplying water under high pressure for the washing of such vehicles and the like. For example, U.S. Pat. No. 6,189,811, issued Feb. 20, 2001 to David Rudy, describes and illustrates a portable pressure washing system having a solar-voltaic power supply, to deliver a pressurized stream of water.

U.S. Pat. No. 5,975,423, issued Nov. 2, 1999 to Terrence D. Rice, teaches of a portable, fully self-contained pressure wash-down system, wherein the components are contained in a single enclosure, for storage and transportation thereof. Unfortunately, due to the weight of the enclosed components comprising the washing unit, i.e. battery, pump and motor unit, as well as the hoses, water supply means, and various nozzles, the system is rather heavy and burdensome to transport long distances.

Along these same lines, in an effort to help minimize the weight of these portable systems and make them less burdensome, smaller pumps implementing less heavy motors are generally utilized, thereby providing a significantly less powerful stream of water than may often be desired for a given purpose. Furthermore, the length of hose incorporated with these portable systems is limited to the small amount of storage space provided within the unit, often requiring the operator to frequently move the pressure-washing system from area to area when washing a large boat or RV.

Because of the aforementioned shortcomings of the prior art in this field, there is a need for a pressurized washing system with a more powerful pumping system, providing increased pressure delivery over the portable systems for use on vehicles such as boats or RV's, which can be permanently mounted and incorporated within such vehicles eliminating the burdensome transportation, unpacking, and setting up required by the portable systems of prior art.

SUMMARY OF THE INVENTION

It is therefore an object of the present invention to provide a self contained pressure washing system to be permanently mounted within a boat or in the alternative, an RV.

Another object of the present invention to provide a pressure washing system which can be fully integrated and hard wired into a boat's generator or shore-power supply, eliminating the need for extension cords or alternative power means.

It is also an object of the present invention to provide a pressure washing system for a boat having its own fresh water reservoir, in connection with an exterior filling means such as a remote quick connector fitting on the side of the vessel.

Another object of the present invention is to provide for an easily storable supply of hose, long enough to allow the user to wash all aspects of the boat or vehicle, eliminating the burden of coiling and storing lengthy hoses.

A further object of the present invention is to provide an easily accessible location on the boat or RV to access the remotely stowed hose supply, and having a quick-connector means for attachment of a spray nozzle thereto.

Finally it is an object of the present invention to provide a fully integrated pressure washing system which can easily be incorporated into both newly manufactured vehicles, and retrofitted into older, existing boats or RV's, without sacrificing a significant amount of space there within.

The foregoing objects are accomplished in the preferred embodiment of the invention by providing a boat mounted pressure washing system, to be fully integrated and mounted within the boat. The pressure washing system comprises an internally mounted pump and drive unit, a fresh water reservoir, and a high pressure hose of predetermined length, and may be mounted in a variety of locations within the boat, such as the bilge, engine room, or storage cabinet. The fresh-water reservoir is hooked up to an external filling means having a quick connector located remotely on side of the boat for attachment of a dock-side hose, and supplies water to the pump unit. The output from the pump is connected to the high pressure hose, storable on an adjacent or remotely located recoiling hose reel. The length of the hose is determined by the users individual preference, but is generally long enough to reach the entire length of the boat and immediate surrounding areas such as the dock.

The distal end of the hose is guided through a sleeve running inside the boat, and terminates in a quick-connection fitting positioned within an aperture on the exterior surface of the boat for connection with a nozzle of preference. When desired to activate and use the pressure wash system, the operator simply energizes the pump unit by turning on a corresponding power supply switch on the fuse panel of the boat, connects a nozzle to the fitting located on the end of the hose accessible through the aperture in exterior surface of the boat, and draws out the desired length of remotely stored hose to begin use.

Once finished, the user simply shuts off the power switch, removes the nozzle, and with the assistance of the spring-recoiled hose reel, simply guides the hose back through the access aperture located within the interior spaces of the boat.

As stated above, further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter, such as integrating the system into an RV or trailer. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. Referring now to FIG. 1, the boat mounted pressure wash system 10 is shown, incorporated and in use with a boat 12. The mounting location within the boat 12, and actual type of boat 12 with which the pressure wash system 10 is shown is not intended to limit the scope of the present invention's applications. Specifically, in an alternative application not illustrated, the pressure wash system 10 of the present invention may be mounted in conjunction with a recreational vehicle (RV) or camper trailer.

Referring now to FIGS. 1 and 2 together, the individual components of the pressure wash system 10 are more clearly illustrated. Comprising four primary components; a fresh water reservoir 20, a pressurizing pump 30, a hose storage reel 40, and a high pressure hose 50 of predetermined length, the pressure wash system 10 may be mounted either unitarily as a whole, or separated so as to allow individual components to be remotely located, providing more flexibility for the system 10 to be adaptable to individual boat applications.

The fresh water reservoir 20 used for holding a supply of water for the pressure wash system 10, has a predetermined volume and is mounted within the interior spaces of the boat, such as the bilge or engine compartment. Other mounting locations such as within a storage cabinet or closet may also be utilized depending upon the users preference, available space and ease of accessibility. The reservoir has a general water supply line 22 connecting between the reservoir 20 and the outside surface of the boat 12, whereby terminating in a universal hose fitting 24. The reservoir 20 is easily refilled with fresh water when depleted, by attaching a hose from the dock-side water supply to the universal fitting 24 located on the outside of the boat 12. The installation of the water supply line requires only minor modification to the boat 12 in terms of cutting a single aperture 25 in the desired, location on the boat 12, proximal the mounted reservoir 20 within the boat, and routing the supply line 22 between the reservoir 20 and the fitting 24 mounted through the aperture 25.

While specific reference has been made above to using a dockside water for the water source utilized by the pressure wash system, the present invention is intended to further encompass applications where the water source for the wash system is provided by water stored in the built in on-board water tanks, commonly provided on both marine vessels and recreational vehicles. In the alternative, the reservoir 20 may be filled with water directly pumped in from the lake or ocean for wash down purposes, when it is not necessary to utilize freshwater.

The reservoir 20 further connects to a pump supply line 26 which feeds water stored within the reservoir 20 to the pressurized pump 30 during use of the pressure wash system 10. The pressurized pump 30 is of a high pressure liquid pumping unit readily available on the market, and generally will be one universally used for all applications of the system 10. Alternatively, a plurality of different pumps 30 may be implemented, depending on individual users performance preference, but regardless of which type of pump 30 is utilized in each installation, the drive motor implemented in the pump will be of marine grade, having sparkless brushes for marine applications. The pressurized pump 30 motor is designed to be hard wired directly into the boat's AC shore supply or generator power supply 32, eliminating any need for extension cords, or additional circuitry when energizing the pump 30 motor. By providing a means for the pump 30 to be energized with either AC shore power or generator power, the pressure washing system 10 may be utilized while the boat 12 is out to sea, thereby supplying the pump 30 with power from the boat's generator. In the alternative, while the boat is docked, the pressure washing system 10 may be utilized wherein the pump 30 may be energized with AC shore power supplied to the boat by a power cord from the shore, thereby conserving fuel in not requiring the boat's 12 generator to be operating continuously. A circuit breaker dedicated to the pressure wash pump 30 is remotely located on the fuse panel of the boat 12, whereby the power supply 32, either shore power or generator provides for energizing the pump 30 when the user activates the circuit.

The pump 30 supplies a pressurize supply of water from the reservoir 20 to a high pressure hose 50 of predetermined length by means of a pressure supply line 41 connected to the permanently mounted hose reel 40 located inside the boat 12 either proximal to the pump 30, or located elsewhere within the boat. The hose reel 40 of which several currently marketed designs may be utilized with the system 10, releasably stores the high pressure hose 50 in a series of coils upon the reel, and has a spring loaded or electromechanically assisted recoiling means 42, for selectively winding or unwinding the hose 50 from the hose reel 40. The recoiling means 42 allows the user to withdrawal the hose 50 from the reel 40 when so desired, lock the reel at any position to utilize the pressure wash system 10, and subsequently provide for returning the hose 50 to the reel 40 when finished. The hose reel 40 also depicted in FIGS. 4 and 5, has a slidable guide means 44 attached to a lateral track 46 implemented into the reel 40, for guiding the hose 50 evenly onto the hose reel 40 during recoiling. The specific length of the high pressure hose 50 is predetermined by the user's preference and available storage space, but generally when fully extended, will be of a length significantly longer than the length of the boat 12 upon which the system 10 is mounted, thereby providing for enough hose 50 length to wash the entire boat 12 and surrounding areas.

Referring now to FIGS. 3, 4, and 5, the distal end 52 of the high pressure hose 50 is fed from the reel 40 through a flexible sleeve 54 having a greater inside diameter than that of the high pressure hose 50. The sleeve 54 provides for a guiding means to slidably guide the high pressure hose 50 from the remotely mounted hose reel 40 to an aperture 56 located remotely outside the boat 12. The distal end 52 of the hose 50 outside the boat 12, terminates in a quick release fitting 58 for attachment to a removable spray nozzle 60, and further has a recoil-stop means 55 located on the distal end, providing for a preventative means of full retraction of the hose 50, into the inside of the boat 12 due to the recoiling means of the hose reel 40. The recoil-stop means 55 comprises an annular bushing of rubber or plastic, having a greater diameter than the aperture 56, thereby preventing full retraction of the distal end 52 of the hose 50 into the boat 12.

Referring to FIGS. 4 and 5, the aperture 56 and corresponding high pressure hose 50 access may be positioned in a variety of locations on the outside of the boat 12 pursuant to the users preference and accessibility, whereby installation requires only minor modification in terms of cutting a single hole in the desired, remote location on the boat 12. Specifically, FIG. 4 shows the hose access aperture 56 on a horizontal deck surface 13 of a boat 12, wherein an alternative embodiment of the present invention, FIG. 5 shows the hose access aperture concealable within a cabinet or access panel 15.

As mentioned above, the scope of the present invention is not intended to be limited to installations on boats of either power or sail. The pressure wash system 10 may be just as easily adapted for mounting in conjunction with a recreational vehicle (RV) or camper trailer, and can be installed during the manufacture of new vehicles, as well as being retrofitted into older, existing boats or RV's.

It may be desirable in the use of the pressure wash system 10 to provide a means of varying the pressure of the water delivered through the nozzle from a forceful stream used to blast off hardened deposits, to a gentle spray for more delicate applications such as windows. As illustrated in FIG. 6, a plurality of means may be employed to achieve the variable pressure desired. A first means may comprise a rotatable dial 62, which electrically connects to the pump motor of the pressure wash system through cord 64. The dial 62 allows the operator to change the speed of the pump motor and thus, the pressure of the water being delivered through the nozzle 60 by hose 50 through fitting 58.

In the alternative, a variable positioned trigger 66 may be employed for serving a similar purpose. The trigger 66 operates to selectively vary the amount of water being delivered through the nozzle 60 by increasing or decreasing the aperture through which the water exits the nozzle via a ferrule extending there through the discharge orifice as the trigger 66 is pulled back, or released respectively. It should be known that this type of nozzle design is well known in the art, but novel in view of its application in the present invention.

A further alternative means of regulating the pressure of water delivered by the nozzle 60 may be a selectably rotatable collar 68, which may operate to extend or retract a ferrule, changing the size of the discharge orifice, similar to the trigger 66 described above. Another way of accomplishing this would be for the collar 68 to directly constrict or dilate the aperture by means of closeable membrane or other means known in the art.

One additional advantage of the present invention may be a means of directly supplying a cleaning liquid such as soap, wax or degreaser while utilizing the power wash system. FIG. 7 illustrates one embodiment wherein a solution container 72 is threadably attached to the nozzle 60 by means of connection 72. The contents of the container 72 are in fluid connection with the water delivered through the nozzle 60 by hose 50. As water is expelled through the nozzle 60, the solution within the container 72 is drawn out through venturi action and mixes with the water being delivered onto the desired surface, thus increasing the power washers capabilities.

Finally Referring now to FIGS. 8 a and 8 b, an alternative to utilizing a hose reel 40 for storage means of the hose 50 is shown. Specifically, the hose utilized in the pressure wash system may be of the precoiled type, having a tightly coiled helical disposition when not in use as shown in FIG. 8 a allowing for easy storage. When it is desired to use the pressure wash system, the coils in the hose 50 are easily stretched out longitudinally to the desired length allowing for the user to operate the pressure washer as so desired.

The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
